1. Slide 1: EPIC Perl Coding YAPC::NA 2007 Houston, TX Josh McAdams
2. Slide 2: Quick Audience Poll How do you edit your Perl code?
3. Slide 3: Sweeping Generalizations Ask just about any Perl programmer what he or she uses to edit Perl and you'll get any one of a hand-full of typical answers: - vi (the editor of the beast vi vi vi) - emacs (rms didn't get rms for no reason) - BBEdit - some random windows text editor - Notepad - UltraEdit basically, it all boils down to...
4. Slide 4: [ This Slide Intentionally Left Blank]
5. Slide 5: Text Editors Most of these environments are extremely powerful and can get the job done, but they have a problem... ... they can be intimidating
6. Slide 6: √ √
7. Slide 7: IDEs Yes, most Perl programmers imagine the worst, but a decent IDE really isn't bad to have in your toolkit. There are a few IDEs out there: - The Open Perl IDE - Komodo - Enginsit's Perl Editor - Affrus - Eclipse
8. Slide 8: Eclipse Eclipse isn't just a Java IDE, it's actually a pluggable application framework... And one of those plugins happens to be EPIC, an Eclipse plugin for Perl integration.
9. Slide 9: EPIC What is EPIC? - an Eclipse plugin that customizes the IDE for Perl development What does it do for me? - syntax highlighting - edit-time syntax checking - code assistants - quick references to perldoc - outline of used modules and subroutines - in-editor source formatting (perltidy) - HTML export - code templates - RegExp plugin - Perl debugger integration (even for web development)
10. Slide 10: EPIC – The IDE

24. Slide 24: EPIC – Code Folding Code folding
25. Slide 25: EPIC – Toggle Comments Comment Toggling
26. Slide 26: EPIC – Toggle Comments TODO Lists
27. Slide 27: EPIC – Refactor
28. Slide 28: EPIC – Refactor Select the code to refactor and choose to 'Extract Subroutine'
29. Slide 29: EPIC – Refactor Give the new sub a name
30. Slide 30: EPIC – Refactor Watch as a sub is magically created for you
31. Slide 31: EPIC – Refactor But it's not that smart
32. Slide 32: EPIC – Refactor Still, an easy fix
33. Slide 33: Understanding Eclipse - Eclipse thinks in workspaces, projects, views, and perspectives - A workspace is just a location of your code on the disk - A project is a group of files that logically fit together, sort of like a Perl distribution - A view is just a window in the interface that provides some sort of functionality... an editor, and outline, etc. - A perspective is a grouping of views that help you effectively do the task at hand... debugging, code editing, etc.
34. Slide 34: When To Use Epic - Epic thinks in projects, it is part of a Java IDE, it can be slow to load and a little overkill for smaller projects. - Epic/Eclipse is really good at helping you manage large projects with multiple files and other resources. - Eclipse can be integrated with SVN, database browsers, and many other tools that can consolidate all of your project tools into one interface.
